NAME
fstab, mtab - list of file systems to mount, mounted file system table. SYNOPSIS
/etc/fstab /etc/mtab DESCRIPTION
/etc/fstab is a table of file system to mount at boot time, /etc/mtab is a table of currently mounted file systems as maintained by mount and umount. /etc/fstab is not read by mount as it should be. It is instead a simple shell script listing the three devices that Minix needs to oper- ate: The device names of the root file system, the temporary (scratch) file system, and the file system for /usr. Of these only the /usr file system is mounted in /etc/rc, the scratch file system is there for the system administrator to test new kernels, or as a temporary file system. /etc/mtab contains lines of four fields. The layout is: device directory type options These fields may be explained as follows: device A block special device. directory Mount point. type Either 1, or 2, indicating a V1 or V2 file system. options Either ro, or rw, indicating a read-only or read-write mounted file system. FILES
/etc/fstab Shell script naming three important file systems. /etc/mtab List of mounted file systems. SEE ALSO
